Abstract
Abstract Connector means are disclosed for connecting together two shaft members in coaxial relationship and in preselected angular orientation with respect to each other. The connector means includes a locking bracket which is secured to one end of the first of the shaft members and a receiver which is secured, by way of an adapter, to the end of the second shaft member. The receiver includes a chamber open at its upper end for slidingly receiving the locking bracket. Both the locking bracket and the receiver have radial extensions which extend in the same radial direction relative to the axis of the coaxial shaft members. Supported on the extension of the locking bracket is a housing containing a spring-loaded pop pin having a nose portion adapted to pass through a hole in the locking-bracket extension and into a hole in the receiver extension, thereby to lock the bracket in the receiver. The pop pin is quickly retractable to unlocked position by a cam manually controlled by a lever. A receiver adapter secures the receiver to the second shaft. The connector means disclosed are particularly adapted for use in X-ray examination equipment where the image-intensifier assembly is mounted on the second shaft.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
230 words
Connector means for quick connection and disconnection of coaxially aligned first and second cylindrical shaft members in preselected angular orientation with respect to each other, said second shaft member having an end flange, said connector means comprising: a. an adapter connectable to said end flange of said second cylindrical members, said adapter including a portion having a key-hole shaped cross-section; b. a locking-bracket receiver having a lateral portion of circular C-shaped cross-section for receiving the cylindrical upper portion of said key-hole shaped adapter; c. said receiver having a vertical portion of flattened C-shape cross-section forming a chamber, said vertical portion including an upward extension having a hole for receiving a lock pin; d. a locking bracket having a body portion having a cylindrical bore for receiving said first cylindrical member, said bracket having a vertical extension corresponding to the vertical extension of said receiver, said extension having a hole therethrough for receiving a lock pin; e. a housing having a lock pin therein; f. means mounting said housing onto said vertical extension of said locking bracket such that said lock pin is aligned with said hole; g. spring means urging said lock pin toward said hole in said locking-bracket extension; h. lever-and-cam means for maintaining said lock pin in said holes in said locking bracket and receiver, and for retracting said lock pin, and for maintaining said lock pin retracted.
Claim 2
Dependent Claim
230 words
Connector means for quick connection and disconnection of coaxially aligned first and second cylindrical shaft members in preselected angular orientation with respect to each other, said second shaft member having an end flange, said connector means comprising: a. an adapter connectable to said end flange of said second cylindrical members, said adapter including a portion having a key-hole shaped cross-section; b. a locking-bracket receiver having a lateral portion of circular C-shaped cross-section for receiving the cylindrical upper portion of said key-hole shaped adapter; c. said receiver having a vertical portion of flattened C-shape cross-section forming a chamber, said vertical portion including an upward extension having a hole for receiving a lock pin; d. a locking bracket having a body portion having a cylindrical bore for receiving said first cylindrical member, said bracket having a vertical extension corresponding to the vertical extension of said receiver, said extension having a hole therethrough for receiving a lock pin; e. a housing having a lock pin therein; f. means mounting said housing onto said vertical extension of said locking bracket such that said lock pin is aligned with said hole; g. spring means urging said lock pin toward said hole in said locking-bracket extension; h. lever-and-cam means for maintaining said lock pin in said holes in said locking bracket and receiver, and for retracting said lock pin, and for maintaining said lock pin retracted.
Claim 3
Dependent Claim
93 words
Connector means according to claim 1 wherein: a. said adapter has a horizontal cavity in its lower portion; b. a spring-loaded plunger within said cavity; c. the wall of said vertical portion of said receiver has a hole therethrough for receiving the head of said spring-loaded plunger; d. said plunger has a shank which extends horizontally through said adapter housing and has a slide block affixed to its external end; e. said slide block has a horizontally projecting pin adapted to enter a notch in said end flange of said second cylindrical member.
Claim 4
Dependent Claim
26 words
Connector means according to claim 2 wherein said receiver chamber is open at its upper end into which said locking bracket is adapted to be inserted.
Claim 5
Dependent Claim
52 words
Connector means according to claim 3 wherein said locking bracket has a camming surface at its lower end, said camming surface adapted to engage the head of said spring-loaded plunger and to cause said plunger to move said slide-block pin into said notch in said end plate of said second cylindrical member.
